Benefits of technology

[0014] In accordance with the present invention, an occlusion device is provided that has a carrying frame with a thin film mesh structure extending over at least a portion of the carrying frame and secured thereto. The thin film mesh structure may cover the carrying frame, line the interior of the carrying frame or the carrying frame may be nested between two layers of thin film. The carrying frame and the thin film mesh structure each have a contracted or collapsed p...

Problems solved by technology

Accordingly, the methods described therein are time-consuming and complicated because of the need to alternate between film and sacrificial layers.
When occlusion d...

Embodiment Construction

[0031] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate manner.

[0032]FIG. 1 illustrates an occlusion device 10 in a collapsed position. The occlusion device 10 comprises a carrying frame 12 and a thin film mesh structure 14 which extends over and attaches to the carrying frame 12. The thin film mesh structure 14 is preferably formed by physical vapor deposition onto a core or mandrel, as is generally known to those skilled in the art. Most preferably, a thin film mesh structure of nitinol, or other material which preferably has the ability to take on a shape...

Abstract

Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Such an occlusion device includes a thin film mesh attached to a carrying frame. The carrying frame is moveable between a collapsed configuration and an expanded configuration. The thin film mesh can include a plurality of slits, slots and/or pores that typically vary in degree of openness as the carrying frame moves between the collapsed and the expanded configurations. The occlusion device is positioned within a blood vessel so that the thin film mesh substantially reduces or completely blocks blood flow to a diseased portion of a blood vessel.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority from provisional patent application Ser. No. 60 / 610,781, filed Sep. 17, 2004, which is hereby incorporated herein by reference.FIELD OF THE INVENTION [0002] This invention generally relates to medical devices that are implantable within a human subject and that have occlusion capabilities that are especially suitable for use as medical device plugs for defective or diseased body vessels. These types of devices have porosity characteristics, upon deployment, that are suitable for enhanced occlusion or other therapeutic capabilities at selected locations. DESCRIPTION OF RELATED ART [0003] Medical devices that can benefit from the present invention include those that are characterized by hollow interiors and that are introduced endoluminally and expand when deployed so as to plug up a location of concern within the patient. These are devices that move between collapsed and expanded conditions or configuratio...
